Fix create_function() deprecated PHP function in WordPress - Faizan Yasin

If you turn on WP_DEBUG, you may find an error like this:

Deprecated: Function create_function() is deprecated in /wp-content/themes/your-theme/functions/widgets/widget-categories.php on line 106

To fix, change this:

add_action( 'widgets_init', create_function( '', 'return register_widget("Woo_Widget_AdSpace");' ), 1 );

to this:

add_action ( 'widgets_init', 'Woo_Widget_init_AdSpace' );
function Woo_Widget_init_AdSpace() {
return register_widget('Woo_Widget_AdSpace');
}
